microSD Shield Assembly and Testing
Activity Objective
- Assemble Sparkfun’s microSD Shield
Equipment Needed
- (C) Soldering station
- (S) microSD shield
- (S) stackable header kit
- (S) \(10 k\Omega\) resistor
- (S) SPDT Switch
- (S) Wire
(C) - In classroom, (I) - provided by instructor, (S) - provided by student or in kit
Activity Procedure
Procedure 1:
- Review Sparkfun’s Arduino shield tutorial on how to solder stackable headers to an Arduino shield found here.
- Complete the soldering steps for the microSD shield found here.
- Run the first example sketches found here.
- Raise your hand and demonstrate to the instructor that the example sketch works. If you receive a “Wiring is correct, and a card is present.” message, your shield is correctly assembled. If you receive an “initialization failed.” message, double-check your soldering and make sure all the joints are correct. Successful completion of the first example sketch will determine your quiz grade.
Procedure 2:
- Review the different regions of the Sparkfun microSD shield shown below Figure 1. Note region 1, the prototyping area. Each hole in the prototyping area is disconnected from everything. In order to connect components in the prototyping area, a wire or solder bridge must be placed between the two holes that the components are in.
- Review the switch circuit shown below in Figure 2.
- Review the switch circuit implemented within the prototyping area of the microSD shield shown below in Figure 3. Both a front and back view are provided.
